Letters Patent No. 105,190, dated July 12, 187;

IMIPROVEMENT IN' GAS-MACHINES.

The Schedule refe! red to in these Letters Patent and making part of the same.

To all whom it may concern Be it known that I, JOSEPH I. GALLAGHER, of the city and county of St. Louis, in the State of Missouri, have invented certain Improvements in Gas-Generators; and I do hereby declare that the following is a full, clear, and exact description thereof', reference being had to the annexed drawing making part of this specification, in which- Figure l is a front elevationof my Vimproved generator, showing the tank for containing't-he gasoline, the pipes for filling the same and for discharging the gas, the bellows, the air-chamber, the pipes forconducting the air to the gasoline-tank, and the mechanism for operating the bellows.,

` Figure 2 is an end view of the same, the end of the gasoline-tank being removed to show the arrangement of the air-induction pipes and the carbureter, which fioatsupon the surface of the contents of the tank.

Figure 3 is a perspective view of the carburetor shown in fig. 2.

Figure 4 is an axial section of one of the bellows, showing its valves.

ACorresponding letters referto corresponding parts in the several figures.

This invention relates to that class of gas-generators which produce gas from a mixture of atmospheric air and gasoline; and p It consists in certain means for improving the quality ofthe gas, and in the combination and arrangement of the apparatus, as wilt be more fully described hereinafter.

A, in the drawing, refers to a frame or table upon which the various parts of the machinery are supported. It may be constructed as shown in the drawing, or in any other suitable manner. .y

B B refer to frames of' metal, which are placed upon v'and secured to the table A, at the proper distance from each other, to enable them to receive and support, in

bearings formed therein, the endsof shafts@ and D1,l

soon to be described, the one marked B being also provided with a bearing for the counter-shaft, which carries the wheels Di and D5.

O refers to a standard, which is secured to the table A, its upper end being bifurcated to receive a groovcd roller, over which a cord or rope passes.

D refers to a shaft which has its bearings in boxes formed in or npon the frames B B.

This shaft extends beyond the bearing 1n frame B', and carries upon its extreme outer end a crank, E', and, nearer to the frame, a ratchet-wheel, E, and a spur-wheel, D6, while just inside of the frame there is another spur-wheel, which meshes into a pinion on shaft D1.

The arrangement of these parts is such that, upon l`turning the crank upon the outer end of the shaft D,

motion will be imparted to such shaft, it rotating within the wheel D, the movement being such as to permit the dog to pass over the teeth of the ratchetvwheel while winding up the machine, but compelling all ofthe parts to move together when thc machine is in operation.

D]l refers to another shaft, which has its bearings in frames B and B', it being provided with a. pinion, D", which is driven by the spur-wheel D4, upon the shaft D.

lfhis shaft is also provided with au eccentric, which is arranged directly over the center of the bellows F, it being connected therewith by means' of a rod and a strap, so that, as the shaft is rotated, a reciprocating movement is given .to the upper head of the bellows.

E E refer to the crank and ratchet-wheel above alluded to, figs. 1 and 2, showing how they are con structed 'and arranged.

F refers to the bellows, the lower head of which is firmly secured to the table A, and is provided with an induction-valve, covering the induction-aperture, which extends through the table, and an eduction-valve, opening outward, to permit the air to pass out. The upperhead of this bellows is provided with a socket or clamp, to which to attach the end of the eccentric rod, in order that motion maybe imparted to said npper head, and' thus air be forced into the receiver through a pipe connectingit with the bellows.

F' refers to a receiver, which is secured to the table A, it consisting of an elastic vessel, in form somewhat like a bellows; or it may be an India-rubber bag, or any other form of vessel which will receive the air from the bellows, and deliver itin a continuous stream into the tank which contains the material from which the gas is made, or which forms a constituent part thereof.

Grefers to a weight which is attached to the outer end of a rope, G2, which passes over a groovcd pulley in the upper end of the standard C, and from thence to and around the shaft D, so that, as said shaft is rotated by the crank, such cord or'rope will be wound around the shaft, it being secured thereto, near one of its ends, by a hook which is inserted therein. When vthe weight G is wound up to the position shown in g. 2, the crank should be removed from the shaft, when the weight, acting through the rope G2, will pnt the parts in motion, as above described, and air will be forced into the tank which contains the gasoline.

H refers to a vessel which is secured to the under side of the table A. It maybe of cylindrical form, as shown, or of any other suitable forni that will enable it to contain the material to he used, and to receive the pipes which conduct the air to it.

I refers to the air-pipe which conducts the air fi'orn the receiver F to the tank or reservoir H. It consists of a single pipe from the receiver to the tank, which it' enters, after which it has several branches, as shown, in order that the air may be delivered Aat different points of the same, and thus a more complete admixture with the gasoline he effected.

K refers to a pipe which connects the bellows with Vthe receiver.

L refers to a pipe through which the gasoline or other material may be introduced into the tank or vesbuoys,"to cause the oat to rise and remain upon the surface of thematerial contained in the vessel.

The central portion of this oat is to be filled with pulverzed charcoal, Vto which may be added a small.

quantity of sulphate of zinc, its walls being nely 'pert'orated, so as to permit the gasoline or other material to circulate freely through it, in order that it may be thoroughly earbureted before passing, from the tank or vessel.

This float is to be of such dimensions that it will float upon the surface of the material, and bythe sides of or between the air-induction pipes.

I also propose to use sulphate of zinc in the vessel in which the gas is generated, which shall be in direct contact with the gasoline, so that it may act mechanically upon the gas, and thus purify the same, and4 cause it to giveV a clearer and more brilliant light.

Having thus described my invention, i

What I claim, and desire tosecure by Letters Patent, is-

1. The carbureting-float herein described, constructed with perforated walls, inclosing the main chamber for containing the purifying material, and air-tight compartments at each end, substantially as set fort-h.

2. In combination with the tank containing the hydrocarbon, the carbureting-doat herein described, to be partially filled with charcoal and sulphate of zinc, or with charcoal alone, substantially as and for the purpose set forth.

In testimony whereof I have signed my name to this specification in presence of two subscribing witnesses.

Witnesses: JOSEPH I?. GALLAGHER.
